When Percy Jackson is kicked out of school because of laistrygonians, he makes his way to Camp Half - Blood to find out that the camp is being attacked, and someone has poisoned Thalia's Tree that keeps monsters away from the Camp.
Percy wants to go on a quest, but instead Clarisse, daughter of Ares, volunteers. Percy and Annabeth and their new friend Tyson go off on a sneak quest where they learn that this quest is just another chess play of their old friend Luke...
In The Sea of Monsters, our heroes encounter dozens of new monsters including rainbow horses, repulsive cannons, and people turned into guinea pigs.
